The present invention seeks to decrease the number of pixel defects in an IPS liquid crystal display device. A gate electrode is formed on a TFT substrate, while a gate insulating film is overlaid on the gate electrode. A pixel electrode which is divided into segments is formed on the gate insulating film. The segments of the pixel electrode are normally interconnected by a source electrode. An inter-layer insulating film, on which a common electrode including slits is formed, is overlaid on the pixel electrode. In a case where the common electrode and one of the segments of the pixel electrode are conductively interconnected by a conductive foreign substance, the other segments of the pixel electrode are allowed to operate by disconnecting the conducted segment of the pixel electrode from the source electrode. Thus, one pixel is prevented from lapsing into a full pixel defect.

A method of fabricating a fringe field switching (FFS)-liquid crystal display (LCD) device may have the following advantage. An inferior connection between the drain electrode and the pixel electrode may be prevented by preventing formation of a copper compound on the drain electrode, by performing a back channel etching after patterning a pixel electrode, and by performing a wet strip rather than a dry strip. This may result in a direct contact between copper and ITO, thereby reducing the number of mask processes.

Common bus design for a tft-lcd display

Номер: US20130045762A1
Автор: John Z. Zhong, Shih Chang Chang
Принадлежит: Apple Inc

Embodiments of the present invention provide for a FFS TFT LCD with a high refresh rate without limiting the aperture of individual pixels. More specifically, embodiments of the invention provide for the use of common bus lines to reduce the effective resistance of the common electrode and to therefore allow for higher refresh rates of the display. Furthermore, the common bus lines can be positioned in such a manner so that they do not further reduce the aperture of the display. More specifically, the common bus lines can be positioned above or below existing elements of the display that are already opaque. Thus, adding the common bus lines need not reduce the aperture. The above can be achieved by, for example, placing the common bus lines above or below existing non-transparent lines, such as gate lines or data lines.

A flicker of an FFS liquid crystal display device that is driven at a low refresh rate is reduced. In an FFS liquid crystal display, a pixel electrode and a first common electrode included in a liquid crystal element are formed on an element substrate side, and a second common electrode is formed on another substrate (counter substrate) side. By making the first and second common electrodes have the same potential, generation of a residual DC voltage can be suppressed in a pixel. Thus, even when a refresh rate is lowered, change in transmittance of a pixel can be suppressed in a data retention period, so that a flicker can be reduced.

A method of fabricating a fringe field switching (FFS)-liquid crystal display (LCD) device may have the following advantage. An inferior connection between the drain electrode and the pixel electrode may be prevented by preventing formation of a copper compound on the drain electrode, by performing a back channel etching after patterning a pixel electrode, and by performing a wet strip rather than a dry strip. This may result in a direct contact between copper and ITO, thereby reducing the number of mask processes.

The invention provides a liquid crystal display device capable of preventing a reduction in display quality by suppressing the occurrence of flicker during alternating-voltage drive, as well as a method for driving the same. Overshoot drive is performed during a first frame period, which is shortened to such an extent that a “positive effective area” and a “negative effective area” are approximately equal in size. The duration of the first frame period is set to be greater than or equal to a quarter of one frame period at a refresh rate of 60 Hz but less than one frame period. This renders it possible to make adjustments such that luminance is inhibited from abruptly dropping immediately after a polarity change, and also luminance is prevented from becoming excessively high due to overshoot drive, and therefore, the occurrence of flicker due to flexoelectric polarization during alternating-voltage drive can be suppressed.

A plurality of structure bodies (also referred to as ribs, protrusions, or projecting portions) are formed over the same substrate, and a pixel electrode and an electrode (a common electrode at a fixed potential) corresponding to the pixel electrode are formed thereover. An electric field is applied to the liquid crystal layer exhibiting a blue phase by using the pixel electrode that has an inclination and the electrode corresponding to the pixel electrode, which also has an inclination. A shorter distance between the adjacent structure bodies allows a strong electric field to be applied to the liquid crystal layer, which results in a reduction in power consumption for driving the liquid crystal.

An electric field is fit to form between the second electrode and the first electrode, and an electric field is also fit to form between the reflection electrode and the second electrode. The second electrode includes a slit electrode, which includes a plurality of slit portions and a plurality of electrode portions each arranged between adjacent slit portions. The electrode portion at least includes a first strip-shaped portion and a second strip-shaped portion. An extension direction of the first strip-shaped portion intersects with that of the second strip-shaped portion, and the first strip and second strip-shaped portions of each electrode portion are connected at a corresponding bending portion. For orthographic projections in a plane where the substrate is located, bending portions of the second electrode and the reflection electrode are located within the insulation protrusion.

A method for manufacturing an array substrate includes: providing a base substrate; forming gate lines and data lines intercrossing each other, the gate lines and the data lines define multiple pixel units. Multiple pixel regions are formed in each pixel unit, a display electrode having a slit is formed in each pixel region. Each data line includes multiple data line segments. In each pixel unit, each of a part of the pixel regions has a display electrode whose slit is parallel to a data line segment adjacent to this pixel region; each of another part of the pixel regions has a display electrode whose slit is non-parallel to a data line segment adjacent to this pixel region. The display electrodes in each of the pixel units are located at a same side of the gate line to which the pixel unit where the display electrodes are located is coupled.
